Car runs great. He drove it home from my house (4 hours away) with no issues.

There is a huge list that I'm forgetting. Car drives great. Handles great even with the skinnies up front. The car stops like a mofo with the Wilwood brakes up front.
Car went 120 mph on 18 psi on pump gas. I ran the car. Never left on the tbrake. Car has a ton left in it!!! Legal THS car. I would say car is an easy mid ten second car when boost is turned up and launched hard. Ran mid 11's with a 1.9 60' on 18 psi and 19 degrees of timing:) Car is a beast on the street with current tune

Comes with many extra parts including GNX flares (not installed) and brand new front spoilers.

He is asking around $15K or trade for a nice truck for equal or less value (+cash).

Contact me if interested.

These are the pics he sent me...more to come if you are interested. Car is located in Evansville, Indiana

I've taken many Buicks to the track. When I had this one there....I had a lot of people come up and compliment this car. Never really had that happen before lol.
